Answer:

When there is an increase in potassium within the cell, depolarization is generated

Explanation:

Depolarization is the intracellular increase of potassium in the cardiac cell, this is how the resting potential is reached, this state of the cell refers to the fact that the cell does not execute or transmit any signal, it is in a refractory state of signals, since it does not capture any, this is how it prepares and recovers for future action potential.

How would the contractile vacuole of a freshwater amoeba respond if the organism was placed in seawater?
saw5 [17]

Correct answer: B). With fewer contractions


The main function of a contractile vacuole is to maintain the sufficient amount of water in the protoplasm of the cell. For the freshwater amoeba contractile vacuole is needed to pump water and maintain a osmoregulation.

But when it is kept in sea water, more contraction is required to expel the water out of the cell in order to make the environment inside amoeba same as of sea water.

What is a way for scientists to find out out about the internal pats of life science specimens. (I'm doing a crossword and I don
Naya [18.7K]

Dissection is one of the procedures through which scientists can find out about the internal parts of life science specimens.

Dissection in its literal terms is the cutting down of an object. The process involves cutting the parts and organs of an organism to study its anatomical structures. The process should be performed carefully so that the anatomy is not ruined and results are not misinterpreted.

Specimens are the samples related to living organisms used to visualize and study about them. These specimens can be deceased living organisms that are carefully preserved using chemicals. Other structures of the living organisms like their teeth, skin, exoskeleton, horns, etc. can also be considered a specimen.

Answer:

How do insects become resistant to pesticide? ... Upon exposure to insecticides, insects that do not carry the resistance genes die, thus allowing the individuals with the resistance genes to survive and reproduce, creating more resistant insects. With every generation the number of resistant insects increase.

The amount of dissolved oxygen decreases with increase in temperature.

However, in chart 1 it was observed that the amount of dissolved oxygen increases with increase in temperature.

<h3>What is the relationship between dissolved oxygen and temperature?</h3>

Dissolved oxygen is the amount of oxygen dissolved in water at a given temperature. Dissolved oxygen is important to aquatic animals for respiration.

The relationship between dissolved oxygen and temperature is that dissolved oxygen increases with decrease in temperature and vice versa.

Based on chart dissolved oxygen initially had a linear relationship with temperature. This, however is contrary to the expected results.
